RVIZ在MovableText :: setFontName中找不到字体Liberation Sans

Question

I am using ROS melodic on archlinux with the following environment settings:

ROS_ETC_DIR=/opt/ros/melodic/etc/ros
ROS_ROOT=/opt/ros/melodic/share/ros
ROS_MASTER_URI=http://localhost:11311
ROS_VERSION=1
ROS_PYTHON_VERSION=2
ROS_PACKAGE_PATH=/opt/ros/melodic/share
ROSLISP_PACKAGE_DIRECTORIES=
ROS_HOSTNAME=localhost
ROS_DISTRO=melodic

And the font file exists in /opt/ros/melodic/share/rviz/ogre_media/fonts/liberation_sans.fontdef

PROBLEM : rviz works OK with the first tutorial example roslaunch urdf_tutorial display.launch model:=/opt/ros/melodic/share/urdf_tutorial/urdf/01-myfirst.urdf , but when I use model with any joint it throws the following error:

terminate called after throwing an instance of 'Ogre::Exception'
what(): : Could not find font Liberation Sans in MovableText::setFontName

for example : when I run: roslaunch urdf_tutorial display.launch model:=/opt/ros/melodic/share/urdf_tutorial/urdf/02-multipleshapes.urdf it signals the previous error, but when I comment the joint section, it works well.

Questions :

• Can I change the search path for ogre to solve that?
• How can I solve this error?

NOTE: I have reinstalled rviz. I am using archlinux.

The problem is with ogre 1.11 new API.

I have reinstalled rviz using https://github.com/ProfFan/rviz commits.

He has a pull-request here https://github.com/fizyr-forks/rviz/pull/1

And it's working now.
